| Research Abstract |
I studied the eigenvalu problem of the Lame operator, which is obtained from the oscillation property of elastic body. I dealt with the compex domain which is a union several thin regions. The limit system when the thinnes goes to zero, is a 4th order ODE system with a complicated compatibility condtions on the verticies. I also dealt with the eigenvalue problem of a certain Lame operator with the low stiffness coefficient. I obtained the limit system, which is related with the eigenvalue problem of the Stokes operator in a fluid dynamical problem with the Dirichlet condition or the slip boundary condition.
